I just wanted to pass on this really great resource a friend of mine put together, over several years, for Cajun music lovers/historians/musicians.
The web page is essentially a search engine that enables you to search through a ton of recordings to find particular musicians or songs. I've only had the link for four days and I've already used it at least 10 times.
Don't expect to see most new cd's though, as he focuses more on the out of date material thats not so easy to find information on.
